Aeration is the process of moving a relatively low volume of air at ambient temperature through stored grain in order to decrease the grain temperature to the desired level and to reduce the risk of damage or spoilage. The aim of this research was to evaluate and compare the performance of three different strategies for aeration of corn grains during 24 days storage. The following strategies were investigated: continuous aeration, nighttime aeration and aeration at equilibrium moisture content conditions between the grain and the ambient air. Corn grains at two different moisture content levels, 11% (w.b.) and 17% (w.b.), were used. Continuous monitoring of temperature through sensors was done and grain samples were taken for moisture content measures throughout the storage time. All aeration strategies favored temperature reduction of dry and wet grains, but none strategy could maintain homogeneity in temperature inside the grain during the storage. Continuous aeration strategy was the most efficient for wet grains, since it avoided grains heating during storage. Grains moisture content changed during the experimental period and a tendency of drying at the end of the process was observed.
